Sounds to me like it could be impaction... Im no expert in leo husbandry, but i know when a animal lays with its legs back and isnt moving its most likely a impaction.. Mayeb try to force feed her some kind of oil (vegetable oil maybe) im not exactly sure what kind of oil to use but it does sound like impaction IMO! sorry i cant help you anymore tom, and again im not an expert just trying to diagnose with a hypothosis....
